IMPROVED PBGGING MACHINE.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, EDGAR M. STEVENS, of Boston, Massachusetts', haveinvented certain improvements in Awl-Feed Begging Machines, which aredescribed andvrepresented in the following specification, andaccompanying drawing, which gives a sectional view of my machine.

My invention relates to a method of feed-ing the work, in combinationwith other'peculiarly arranged parts of such machines, and consistsamong other things in feeding the work by a movement of the awl when itis connect-ed with a head so hung as to conform to the surfacecurvatures of Ythe sole; and its object is to secure perfect and uniformpegging round short curves or otherwise. This is attained by acombination of the vibrating awl when used asa feeding instrument .witha sliding swinging head, which supports the pegging mechanism andpresents it properly to the work.

In the drawing, A is a casting, which forms a head or support for thepegging mechanism. It has pivots B by which it is hung in slides or waysy y, in which the pivots or axes B B can move upand down, so that it canswing as well as slide, (or it may be made to slide sideways, as well asup and down.) C is a cam-shaft connected to a driving-wheel by a`ioint-link or otherwise, which will permit the various movements of thehead while itrotates the cam-shaft. D, shown by red lines, is the cam bywhich the awl-bar E is raised.- shown by blue lines, is the cam whichgives the awl-bar its sidewise movement. Cr, shown by black lines, isthe cam which lifts the peg-driver bar H. The downward movement of theawl and peg-driver is given by the contraction of suitable springs, whenby the rotation of the cams the projections from the bars are allowed tofall from 4the points D and G. These springs areattached by one end toA. (The awll and peg-driver may he driven down by means of cams orWeights acting as hammers.) The pins a Ia acting on the inclined slotsin the pegdriver during its vvertical movement give it a sidewisemovement, so that the awl-bar will'notl interfere with it, end so thatin the last portion of its rise it will act on the lever b, which actson the catch c, and liberates the peg-tube ci when the spiralspring edraws it to the position shown in the drawing, or the lever band catch cmay be dispensed with, and the lever z' he divided into two partspivoted together at m, andthe lower part pivoted to the frame at 1t, inwhich casethe depression of the bent part of lever z' by the pin willcause the lower part atl i to move the knife-barj to the left andcut'the peg, and the spring k will return it after it has done its duty.The awl will strike through the peg-tube carrier d to the left of thepeg-tube as it descends, and as it moves laterally it will carry thepeg-tube to the right. The withdrawal of the awl will liberate thepeg-tube and allow the spring e to draw it back to its proper positionfor the action of the peg-driven; The awl-bar E is guided in its rise4and fall by the pinsff fitting in slots therein. These pins are fixedin a sliding frame which is guided by suitable ways formed in the head.Another pin, g, fixed in the same frame, projects from it into 'the camF, 'which in itsv rotation by the vmeans described gives the sideways orfeeding movement of the awl. The pin h acts on the bent llever z', whichactuates the knife j by which the pegs are split from the peg-wood. Thespring c also acts on the lever t' to return it to the position itoccupied before the -pin L moved it. The peg-tube cl is secured to thehead by suitable Vslides and ways, and is brought forward by the forwardsidewise movement of the awl when it feeds the work, so that the recesscut therein for the reception of the peg when cut from the wood, andthrough or into which the awl and pegdriver pass, will be in the placeindicated by red lines. In this movement of cl it will raise the catchor latch c, which is so arranged that a spring, Z, will throw the latchc down holding the peg-tube against the action of the spring e duringthe driving of the peg, and until the pegilrivcr is raised nearly to itsfull height. The peg-carrier is represented as broken from the head, asit does not differ from the common peg-carriers. e

The order of driving apeg is as follows: Premisingethatthe cam D isnearly in the position shown in the drawing, rotation of the shaft Ccauses the awl to come down throughV the peg-tube into the work; it isthen moved forward by the cam F, then raised by the operation of'the camD, and then moved back sidewise by the camvI During these operations thepin h has withdrawn the knife and held it until the peg-wood was forcedinto the tube, when the pin rotating beyond the lever z', the spring 7cforces the knife 7' forward, splitting the peg from the wood and formingthe fourth side to the peg-tube. The driver now descends and drives thepeg in the' tube, and at once resumes its former position, in doingwhich it acts on the lever b, which raises the latch c, whichis thenmoved by the spring e under the nwl, and the next rotating of thecam-shaft repeats the operation. When the peg-tube is so placed that therecess cut therein for the reception of thepeg is at'the place indicatedby red lines, the knife is Withdrawn long enough to permit the peg-woodto be forced forward-the knife then advances, cuts the peg from theWood, and remains in this position, formingr the fourth side of aboxenclosing the peg that it may be driven withoutA being bent or broken.

' As'my invention has reference to n sidewise movement of the :Lwl whenused for feeding the work, when combined with n. bend for supporting thepegging mechanism, which has a. sliding, or sliding and swinging move--ment, or a, vertically-and laterally moving head, 'I do not desire tolimit myself to my partieuinrly described mechanism, but have regard tanalogous or equivalent devices for producing similar results inmachines operated by wheel treedle o1' power, and distinct fromhnnd-peggers.

YVhat I claim, therefore, and desire to secure by Letters Patent, is-

l. The combination of a. vibrating moving awl with a. sliding orvertically moving head, substantially as described.

2. Combination of the feeding-:MV1 with the sliding and swinging bend,substantially as set forth.
